Answer:
40 I told u
Step-by-step explanation:
right angles are 90 degrees
Step-by-step explanation:
(1 - cos²A) (1 + tan²A) = tan²A
(sin²A)(sec²A) = tan²A
(sin²A)(1/cos²A) = tan²A
(sin²A)/(cos²A) = tan²A
tan²A = tan²A → <u>Proved</u>
Answer:
Step-by-step explanation:
Given that in a sample of 800 U.S. adults, 199 think that most celebrities are good role models. Two Two U.S. adults are selected at random from the population of all U.S. adults without replacement.
In 800 adults 199 are favourable and remaining 601 are against.
a) The probability that both adults think most celebrities are good role models is ________= Prob of selecting both from 199
= 
=0.062
b) The probability that neither adult thinks most celebrities are good role models is _______=P(both selecting from 601)
= 
=0.564
c) The probability that at least one of the two adults thinks most celebrities are good role models ______
=1-Prob that neither thinks
= 1- 0.564
= 0.436
Since this is a right triangle, we can use one of the three main trigonometric functions: sine, cosine, or tangent.
Remember: SOH-CAH-TOA
Looking from the angle, we know the opposite side and the adjacent side. Therefore, we should use the tangent function.
tan(x) = 19 / 35
x = tan^-1(19/35)
x = 28 degrees
Hope this helps!
We are given the equation:
x^2 + 10x + 11 = m + (x-5)^2 - 25
To determine the value of m, assign a value of x and solve for m
if x = 1, the equation becomes
1^2 + 10(1) + 11 = m + (1 -5)^2 - 25
solve for m
m = 31
When m = 31, the equation is true. <span />
